← ScienceWhich outcome arises when a Carnot heat engine reaches its maximum temperature constraint?
A)Increased frictional thermal energy dissipation
B)Reversible isothermal process stalls
C)Entropy generation rises asymptotically✓
D)Adiabatic expansion rate declines
💡 Explanation
Reaching temperature limit causes maximum temperature difference, thus the maximum theoretical efficiency is achieved. Further energy throughput yields entropy generation rises asymptotically because the ideal Carnot cycle cannot be truly reached; therefore, irreversibilities increase rather than the engine operating more perfectly.
